Having trouble adding a JavaScript to your site?  Just can't get things working?  Add this short script to your site, and it will report to you JavaScript errors as they happen in a box on the screen.  The idea is that you will see what the error is, and hopefully give you some ideas on how to fix it.  I actually use this script when I debug scripts!

<!-- Demonstration -->

<form name=err>
<input type=button value="Cause JS Error" onClick="brokenScript()">
</form><p>
<form name=errform>

<p>Simply click inside the window below, use your cursor to highlight the script, and copy (type Control-c or Apple-c) the script into a new file in your text editor (such as Note Pad or Simple Text) and save (Control-s or Apple-s).  The script is yours!!!
